citizen of the United States, and a resident of New York, in the countyof New York and State of New York, have invented bertain new anduseiiullmproveinents in liinetoscope-Shutter-Settir1g Devices, of whichthe following is a specification.

The invention relates tolrinetoscopes, and

more particularly to a device or attachment to cooperate with theshutter thereof. The device may be built integrally with theiiinetoscope, but is adapted, also, for attachment toeitisting machines,particularly such in which the shutter is hingedly supported in front ofthe lens as for convenience in packing and transportation.

The invention has for its object to so adjust the shutter that there maybe avoided the ghost and the flicker produced on the projected imagewhen the cut-off blade of the shutter is respectively behind or ahead ofa picture in transition. The adjustment may be made in initially settingor timing the apparatus and greatly simplifies this operation; or, itmay be made in case the film and shutter are thrown out of synchronisinin framing, or from lost motion caused by wear. I

The nature "of the invention will be best understood when described inconnection with the accompanying drawings, in which- Figure 1 is a frontelevation er part of a kinetoscope and show the attachment providedthereon. Fig. 2 is a similar view of one side of the kinetoscope.

Similar characters of reference designate corresponding parts throughoutthe several views.

In carrying out the invention, means are provided to efiect a relativeangular adjust ment between the plane of the shutter and the projectinglens (picture image and whereby, though the shutter speed be constant,the time may be varied at which a given portion of a shutter bladearrives at a particular point of the lens or image of picture. This iseffected by tilting the shutter either inwardly or outwardly as the casemay be and as indicated by the positions shown in dotted lines, Fig. 2.The operating means for this purpose, for example, a handle or screw,may be conveniently located Specification. of Letters l atcnt.

respect to the other operating mechanism of the lrinetoscope. in thepresent embodiment, the same is shown located at the side of the frameit oi the kinetoscope and consists or" a spindle 11 mounted to turn insuitable bearings 12 attached to said frame, a milled head 13 beingprovided at the outer end for convenient manipulation. The lens 14(objective) is fixedly secured to the frame 10 in the present embodimentand a shutter 15, for example a rotary shutter of usual design, ismounted before the same, the axis thereof being arranged to lie normallyparallel to the longitudinal axis oi the lens. A shaft 16 to rotate theshutter is i?1- ).iili38l at the side of the kinetoscope in a suitablesupport 17, which is pivotally attached as to the frame 10 upon a stud18 of said frame ;and the said shaft is rotated from the film operatingmechanism of the kinetoscope through worm, 19 at its inner and a gear 20or" said film operating mechanism engaging the worm. Shaft 16 and itssupport 17 may thus be tilted, that is, caused to swing about said stud18 as a center, whereby the plane of the shutter willbe inclined eithertoward or away from a plane perpendicular to the axis of the said lens.

To effect the swinging or tilting, any convenient mechanism may beemployed, and l have herein shown a threaded rod 21 flexibly connectedto the support 17 in manner such that when the rod is raised or loweredthe said support will. be correspondingly swung about stud 18. For thispurpose, the upper end of rod fits into a bearing 22 is provided with aperipheral groove (not shown) into which fits a pin 23 extending throughthe bearing. The bearing, in turn, is pivotally attached to a clamp 24:rigidly held to the shutter support. the attachment to be readilyremoved or secured to a kinetoscope. The rod 21 is raised or lowered bycausing it to pass through the tapped arm 25 of a bifurcated guide piece26 through which passes the spindle 11, the

rotation of said spindle being transmitted to the said rod through apair of bevel gears 27, oneoi which is mounted upon the inner end of thespindle and the other upon the said rod and movable longitudinally withrespect thereto to drive the san e, by means of a pin 28 thereof fittinga longitudinal groove in the said rod.

and

This enables I claim 1. In a kinetoseope: the combination With ashutter, and a lens With which it is adapted to cooperate; of means toeiieet an an gular displacement between the said lens and the plane oisaid shutter.

2. In a kinetoscope: thecombination with a rotary shutter; and a lensWith which it is adapted to cooperate; of means to eilect an angulardisplacement between the said lens and the plane of said shutter.

3., In a kinetoscope: the combination with a pivotally supportedshutter, and a lens with which it is adapted to cooperate; of means totilt said shutter relatively to said lens.

4. In a lzinetoscope: a suitable frame; a

shutter, and a support therefor pivotally' secured to said frame; a lenssecured to said frame and adapted to cooperate with said shutter; andmeans to swing said shutter support.

5. In a kinetoscope: a suitable frame; a shutter pivotally securedthereto; a lens secured to said frame and adapted to coopcrate with saidshutter; and means mounted on said frame to swing said shutterrelatively to, said lens.

6. In a kinetoscope: a suitable frame; a shutter, and a support thereforpivot-ally secured to said frame; a lens secured to said frame; a rodflexibly secured to said shutter support; and means secured to saidframe to advance and retract said rod.

7. In a kinetoscope: a shutter support; and means to tilt the sameindependently of the projecting lens of the kinetoscope.

8. In a kinetoseope: a pivoted shutter support; and means iemovablyattached to said hinetoscope to tilt said shutter support independentlyof the projecting lens of the kinetoseope.
